Encephalitis is also called acute viral encephalitis or aseptic encephalitis.
Encephalitis (in-seh-fuh-LYE-tus) is a rare disease. Most cases happen in children, the elderly, and people with a weakened immune system (from HIV/AIDS, cancer, etc.).
Several thousand cases of encephalitis are reported to the Centers for Disease Control and Prevention (CDC) every year. But health experts think that many more cases happen that aren’t reported because symptoms vary and can be mild.
Symptoms in mild cases of encephalitis usually include:
Serious cases of encephalitis can cause:

Most kids with encephalitis need care in a hospital, usually in an intensive care unit (ICU). Doctors will watch their blood pressure, heart rate, breathing, and body fluids to prevent further swelling of the brain.
Many people with encephalitis make a full recovery. In some cases, brain swelling can cause lasting problem like learning disabilities, speech problems, memory loss, or lack of muscle control. Speech therapy, physical therapy, or occupational therapy can help in these cases.
Most of the time, the
phase of the illness (when symptoms are the most severe) lasts up to a week. Full recovery can take longer, often several weeks or months.
Encephalitis can’t be prevented, but you can avoid the illnesses that may lead to it. Immunizations protect kids from many common childhood illnesses. So follow the immunization schedule recommended by your doctor. Kids should also avoid contact with anyone who already has encephalitis.
It’s also important for everyone in your family to wash their hands well and often.

Chickenpox used to be common in kids, causing a very itchy red rash all over the body. But the good news is that a vaccine can prevent most cases.
Lyme disease can affect the skin, joints, nervous system, and other organ systems. If Lyme disease is diagnosed quickly and treated with antibiotics, most people feel better quickly.
The best way to prevent Lyme disease is to prevent tick bites. Find out more about this disease and how to keep those ticks away.
Lyme disease can be treated if it’s caught early. Find out what causes it, how it’s treated, and how to prevent it.
Fevers happen when the body’s internal “thermostat” raises the body temperature above normal. This is often the body’s way of fighting infections.
